LEONARD D. SOUBIER, TOLEDO, OHIO, ASSIGNOR TO THE OWENS BOTTLE COM- IPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

. GLASS FEEDER.

Application filed October 2, 1922. Serial No. 591,752.

To all whom it may concern Be it known that I, LEONARD D. SOUBIER, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Glass Feeders, of which the following is a specification.

My invention relates to' apparatus for delivering individual masses or charges of glass from a tank or pool of glass. More particularly, it relates to a glass feeder of the type in which the glass is delivered through an outlet opening in the bottom of a furnace boot or other receptacle, the dis: charge being controlled by a vertically reciprocating plug or other re lator. In feeders of this type, considera le difliculty has been experienced on account of chilling and stagnation of the glass in front of the regulator and consequently an unsymmetrical flow'of glass through the outlet. The issuing column or gob of glass being colder on one side than the other causes various defects in the finished ware produced there- 2 from. Attempts to overcome this difliculty by the use of a stationary wall or island behind the regulator for guiding the glass around the latter, have not proved entirely satisfactory. An object of my invention is to overcome the above difficulty by the provision of adjustable uiding means for directing the flow of g ass to and around the regulator,-

said means bein adjustable to meet varying conditions ound in practice, such as variations in temperature, level of the glass, rate of discharge, etc.

Other objects of the invention will appear hereinafter.

In the accompanying drawings: Figure 1 is a sectional plan view of a glasosl feeder to which my invention is apie P Figure 2 is a sectional elevation of the same at the line IIII on Figure 1.

Figure 3 is a front sectional elevation at the line IIIIII on Figure 2, the regulating plug being omitted.

Figure 4 is a plan view, with parts broken away, of adjusting mechanism shown in Fi re 3. I 4

igure 5 is a sectional plan view of a modified form of feeder in which a (plurality of discharge outletsare provide The molten glass 10 is supplied to the charger 11 from the main tank or furnace 12. Said charger is herein shown as comprising the usual furnace boot or extension provided with a well 9 in the floor thereof at the forward end of the boot, said well having an outlet opening 13 .in the bottom thereof. The discharge of the glass is controlled by a regulator 15 which may be the usual clay plug periodically reciprocated in a vertical direction for alternately exerting expelling and retarding forces on the issuing glass.

As the glass flows forward from the furnace and through the outlet 13, there is a tendency for the glass to issue from the outlet mainly at the rear side of the regulator 15, following the path of least resistance. The glass in front of the regulator is, there fore, comparatively inert and becomes more or less chilled, thereby augmenting the unevenness or onesidedness of the flow. As a result, the issuing charges or gobs of glass are unsymmetrical in shape and temperature, being colder on one side than the other. This lack of symmetry produces unevenness and defects 1n the finished ware.

In order to overcome this objection and distribute the flow of glass evenly around the regulator 15, I provide a pair of adjustable guides 16 projecting downward into the glass in the boot. Each guide is carried by a vertical metal rod or core 17,

at the lower end of which is an enlar ement or foot 18 forming a reenforcement or the body 16 which is made of fire clay or other refractory material. Each core 17 is surrounded by a sleeve 18 of fire clay. The

guides 16 are supported by brackets or rames 19 in which the rods 17 are journalled. Attached to each rod 17 near its upper end is a worm gear segment 20 operated by a worm 22 on a shaft 23 journalled in the frame 19 and provided with a hand wheel 24. By rotating either hand wheel 24 the corresponding guide 16 is rotatively adjusted about the axis of its stem 17.

The frames 19 are slidable vertically in guideway 25 formed in the ends of a yoke 26. Adjusting rods 27 journalled in the yoke 26 and having screw threaded connection with the frames 19, are provided with hand wheels 28, whereby either frame 19 may be adjusted vertically independently of the other, thus independently adjusting the guides 16 up or down in the glass. The

the entire mechanism.

' effected.

.- means to adjust said yoke 26 is adjustable vertically, the ends of said yoke being slidablein vertical guideways 29 provided in a stationary framework 80 which forms a support for Adjustment of the yoke 26 is effected by means of a screw rod 32 threaded into the yoke, said rod being journalled in the frame 30 and provided with a hand wheel 33. By rotating the hand wheel 33, the guides 16 are together adjusted up Or down.

' By adjusting the guides or wings 16 to athe Figure 1 position, the greater portion of the glass flowing forward to the outlet is guided along the outer'faces of said guides and thus directed towards the forward side of the regulator 15. By properly adjusting the guides 16, a uniform distribution of the issuing glass around the regulator may be In practice, there is sometimes a tendency for the glass to flow forward around one side of the regulator more freely than the other side, thereby causing an unsymmetrical discharge. This difficulty may be overcome with the use of my invention by adjusting one of the wings 16 at a greater angle than the other. By adjusting the wings vertically in the glass, the amount of glass flowing forward beneath said wings to the outlet without being laterallyv deflected by said wings, may be regulated and controlled. In this manner, a greater or less proportion of the issuing glass may be drawn from the substrata or glass beneath the surface, rather than from the surface layers of glass. This also forms a convenient means for quickly adjusting and controlling the temperature of the issuing glass, as the glass near the floor of the boot is usually at a difi'erent temperature than that at .or near the surface.

Figure 5 shows a modified construction in which a plurality of outlet openings are provided in the boot 11*, said openings being controlled by regulators 15, 15*, and 15. The guides 16 are adjustable to reg-. ulate the relative amount. of glass directed to the respective outlets.

Modifications may be resorted to within the spirit and scope of my invention.
